Summary
Marine alkaloids called lamellarins, discovered in 1985, show promise as anticancer agents. Lamellarin D effectively inhibits topoisomerase I and induces cancer cell death by targeting mitochondria.
Area of Science:
- Marine natural products chemistry
- Medicinal chemistry
- Cancer biology
Background:
- Lamellarins are a class of marine alkaloids first isolated in 1985.
- Over 50 lamellarins have been identified, with numerous derivatives synthesized and evaluated.
- These compounds are explored for their potential antiviral and anticancer properties.
Purpose of the Study:
- To review the chemistry and pharmacology of lamellarins.
- To detail the mechanistic actions of lamellarin D, a lead compound.
- To highlight lamellarins as a foundation for novel anticancer drug design.
Main Methods:
- Literature review of lamellarin chemistry and pharmacology.
- Discussion of lamellarin D's mechanism of action, including topoisomerase I inhibition and mitochondrial targeting.
- Overview of synthetic efforts towards novel lamellarin derivatives and related marine alkaloids.
Main Results:
- Lamellarin D is a potent inhibitor of both nuclear and mitochondrial topoisomerase I.
- Lamellarin D can directly induce cancer cell death through mitochondrial interference.
- Lamellarins serve as valuable scaffolds for developing new anticancer therapeutics.
Conclusions:
- Lamellarins represent a significant class of marine natural products with demonstrated anticancer potential.
- Lamellarin D's dual action on topoisomerase I and mitochondria offers a promising therapeutic strategy.
- Continued research into lamellarin synthesis and derivatization is crucial for advancing anticancer drug discovery.

9.2K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

02:39lncRNA - Long Non-coding RNAs
10.2K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

00:55Laminins are the Adhesive Proteins of Basal Lamina
4.3K
Laminins are heterotrimeric proteins with high molecular mass found in the extracellular matrix. Each laminin molecule is composed of three chains, viz. alpha, beta, and gamma, coded by five, four, and three paralogous genes, respectively. Laminins are categories based on the compositions of the three chains.
In humans, the five forms of alpha chains are LAMA 1, LAMA 2, LAMA 3, LAMA 4, and LAMA 5. The four forms of beta chains are LAMB 1, LAMB 2, LAMB 3, and LAMB 4. The three forms of gamma...

01:10Drugs that Destabilize Microtubules
4.4K
Microtubules are dynamic structures and can be regulated by microtubule targeting agents (MTAs). Microtubule destabilizing drugs are a class of MTAs that destabilize and prevent microtubules' polymerization. Both natural and synthetic chemicals can be found under this class of drugs. Vincristine and vinblastine, two vinca alkaloids, and colchicine were among the first to be discovered. These drugs can affect cells in various ways, either by inducing a change in cell morphology, preventing...

01:15Drugs that Stabilize Microtubules
2.9K
Microtubules are dynamic structures that undergo cycles of catastrophe and rescue. The microtubules play a central role in cell division by forming the spindle apparatus for segregating the chromosomes. This makes them ideal targets for regulating dividing cells in tumors and malignant cancer cells. Microtubule stabilizing drugs help stabilize the microtubule formation and promote its polymerization. Paclitaxel was the first microtubule stabilizing agent used as anticancer drug in chemotherapy...
